Marijuana Shows Potential in Treating Autoimmune Disease


A team of University of South Carolina researchers have discovered a novel pathway through which marijuana’s main active constituent, THC, can suppress the body’s immune functions, reported ScienceDaily.com

Researchers Mitzi Nagarkatti, Prakash Nagarkatti and Xiaoming Yang’s research has been published online in the Journal of Biological Chemistry.

Marijuana is the most frequently used illicit drug in the United States, but as more states legalize the drug for medical and even recreational purposes, research studies like this one are discovering new and innovative potential health applications for the federal Schedule I drug, reported ScienceDaily, adding marijuana is now regularly and successfully used to alleviate the nausea and vomiting many cancer patients experience as side effects to chemotherapy, combat the wasting syndrome that causes some AIDS patients to lose significant amounts of weight and muscle mass and ease chronic pain that is unresponsive to opioids.

The university study has uncovered yet another potential application for marijuana, in the suppression of immune response to treat autoimmune diseases. The work builds on recent scientific discoveries that the environment in which humans live can actually trigger changes that occur outside of human DNA, but nevertheless can cause alterations to the function of genes controlled by DNA, according to the news report.

“These outside molecules that have the ability to alter DNA function are known collectively as the epigenome. In this study, the investigators wanted to find out if the tetrahydrocannabinol (THC) found in marijuana has the capacity to affect DNA expression through epigenetic pathways outside of the DNA itself,” the report reads.

The recent findings show that THC can change critical molecules of epigenome called histones, leading to suppression of inflammation. These results suggest that one potential negative impact of marijuana smoking could be suppression of beneficial inflammation in the body, reported Science Daily, noting the findings also suggest that because of its epigenetic influence toward inflammation suppression, marijuana use could be efficacious in the treatment of autoimmune diseases such as arthritis, lupus, colitis, multiple sclerosis and the like, in which chronic inflammation plays a central role.
